OPINION
Plaintiff-Appellant, Abraham & Rose, P.L.C., appeals the district court’s order granting summary judgment to defendant-appellee, the United States of America, acting through the Internal Revenue Service (the “IRS”), in this action brought under the Freedom of Information Act (“FOIA”), 5 U.S.C. § 552. For the reasons that follow, we reverse and remand,
I. BACKGROUND
In January 1996, pursuant to FOIA, appellant requested access to computerized records of federal tax lien filings 1 from, the Detroit- and Cleveland Districts of the IRS. J.A. at 25-26 (Exs.l, 2). The IRS,, citing various FOIA exemptions, denied appellant’s FOIA requests.. J.A. at 27-29 (Exs.3, 4). Appellant then filed an administrative appeal with the Commissioner of Internal Revenue. J.A. at 34 (Ex. 6). When appellant received no formal response from IRS officials with regard to its appeal within the statutorily set 20-worlring-day response period, appellant commenced this aetion in federal court on May 21, 1996 for declaratory and injunctive relief. See 5 U.S.C. § 552(a)(6)(A)(ii) and 552(a)(6)(C); J.A. at'4 (Compl.).
The district court denied appellant’s motion for summary judgment and instead granted the government’s cross-motion for summary judgment, based on its conclusion that (1) “the information plaintiff seeks is already public information in the various counties”; and' (2) “plaintiffs request appears to be inapposite to the purpose of FOIA” since “[p]laintiff seeks information about private citizens for its own business purposes.” J.A. at 7-8 (Order at 2-3). Having resolved the case on such grounds, the district court decided that it no longer needed to consider whether any exemptions applied to appellant’s requests. ■ J.A at 8 (Order at 3). Both appellant and appellee agree that the district court’s order was grounded on faulty reasoning as a matter of law, but while appellant further contends that the requested information does not fall within any FOIA exemption category, the government argues that it does. The district court had original jurisdiction pursuant to 5 U.S.C. § 552(a)(4)(B). This court has appellate jurisdiction pursuant to 28 U.S.C. § 1291 over *1078 the district court’s final judgment in the instant case.
II. ANALYSIS
A. Standard of Review
Under FOIA, “each agency, upon any request for records which (A) reasonably describes such records and (B) is made in accordance with published rules stating the time, place, fees (if any), and procedures to be followed, shall make the records promptly availablé to any person.” 5 U.S.C. § 552(a)(3). This mandate does not apply however to information that falls within any of nine specific exemption categories listed at 5 U.S.C. § 552(b). An agency’s decision to deny a FOIA request is subject to de novo review by a district court.
See
5 U.S.C. § 552(a)(4)(B);
Detroit Free Press, Inc. v. Department of Justice,
B. Availability through Alternative Sources
Both parties on appeal contend that the district court erred when it decided not to address the applicability of the FOIA exemptions and instead withheld the information requested because it was already public information and available to appellant through a search of county records. J.A. at 7 (Order at 2); Appellant’s Br. at 11-13; Appellee’s Br. at 16-18. The parties are correct that this was an inappropriate basis for exemption under FOIA and that the district judge committed an error of law. In
United States Dep’t of Justice v. Tax Analysts,
C.Purpose of Request
Courts have often commented that one of the main driving forces behind the enactment of FOIA was Congress’s goal of opening up “‘agency action to the light of public scrutiny.’”
United States Dep’t of Justice v. Reporters Comm. for Freedom of the Press,
D. FOIA Exemptions
The proper course would have been for the district court to determine whether any exemptions applied in the instant case and then to deny the FOIA requests to the extent that any did. In general, the agency denying a FOIA request bears the burden of establishing that the information requested falls within' an exemption category.

5 U.S.C. § 552(a)(4)(B);
Kiraly v. FBI,
1. Exemption 2
Appellee’s first claim is that the requested records of federal tax lien filings were properly withheld .from appellant .in their entirety pursuant to Exemption 2 which permits the withholding of materials “related solely to the internal personnel rules and practices of an agency.” See 5 U.S.C. § 552(b)(2). The crux of appellee’s argument is that the records requested by appellant are covered by Exemption 2 simply because such records are generated through the Automated Lien System (ALS) of the IRS, the “electronic database which serves as the Service’s centralized repository of information related to Federal tax liens,)’ Appellee’s Br. at 21 (quotation from J.A. at 73 (Hebert Decl. at 1)). According to Thomas Hebert, the program analyst responsible for the ALS, the database is used as “an internal tool to enable the Service to create and monitor its filings of Notices of Federal Tax Lien.” J.A. at 74 (Hebert Decl. at 2). Notices of Federal Tax Lien are prepared from the data compiled in the ALS, and the database also aids IRS personnel in ensuring the release of such liens when they are satisfied. J.A. at 74 (Hebert Decl. at 2). Some of the information contained in the ALS is incorporated into publicly recorded filings, but other types of information not available in these public records are also contained in the system. 3 J.A. *1080 at 74-75 (Hebert Deel. at 2-3). The requests ed records’ association with the ALS arguably relates to rules and practices of agency personnel in two respects. First, one could argue that the requested records shed light on the IRS’s personnel practice of collecting information through the ALS. Second, appellant suggests that such a relationship exists because the ALS and everything derived from it, including the requested records, were designed solely for internal agency use. However, as the following discussion shows, neither is a sufficient basis for invoking the protections of Exemption 2.
Under the first prong of a two-prong test used to determine the applicability of Exemption 2, the withheld information must come within the terms of the statutory language.

See Schwaner v. Department of the Air Force,
• It is true that information deemed to be related predominantly to personnel rules and practices of an agency need not be actual rules and practices themselves; the information can be so closely related to an agency’s personnel rules and practices that disclosure could lead potentially to their disclosure.
See Schwaner,
However, information that merely has a potential for shedding light
on the practice of collecting and compiling information
is not sufficiently related to a personnel rule or practice to satisfy the first prong under Exemption 2 analysis. In
Schwaner,
the D.C. Circuit rejected the argument that, merely because the information requested in that case — various lists of names and duty addresses of Air Force base personnel — had been exclusively derived from the Air Force’s Advanced Personnel Data System (a compilation of information extracted from various files and databases), they were sufficiently related to internal personnel rules and practices of the Air Force.
See id.,
Moreover, the mere fact that the requested information is part of a system designed specifically for internal agency use and that personnel use the materials in carrying out their responsibilities does not alter this conclusion. Appellee emphasizes the decision in
KTVY-TV v. United States,
No. 87-1432-T (W.D.OHa. May 4, 1989),
affd on other grounds by
In the instant case, the IRS makes too sweeping a claim in arguing that simply because the ALS is an internal database designed for internal use by personnel, this database or the records created from this database shed significant light on a personnel rule or practice. While the ALS aids IRS personnel in carrying out their responsibilities of preparing and monitoring federal tax lien filings, there is no evidence suggesting that the ALS signifies anything more than the IRS’s practice of collecting and compiling information from various sources, like the database at issue in Schwaner. In this sense, the requested records are more similar to the list of names and duty addresses of Air Force base personnel and the maps identifying the location of birds tracked by the U.S. Forest Service than to the ethics hearing summaries discussed in Rose. We conclude that the practice of compiling information is not a personnel practice under Exemption 2 and that this is not any more of a personnel practice simply because the information collected was intended solely for internal use. We thus hold that the requested records’ mere derivation from the ALS as presented by appellant on this appeal is insufficient to create the significant, meaningful relationship with IRS internal personnel rules and practices required by Exemption 2’s statutory language. This decision regarding the scope of Exemption 2 as a matter of law does not, however, preclude the district court from otherwise finding that certain particular pieces or types of information contained on the records of tax lien filings or in the ALS fall within the scope of Exemption 2, as courts have found with respect to confidential FBI informant codes and inter-agency document handling instructions.
2. Exemptions 6 and 7(C)
Appellant also claims protection from Exemptions 6 and 7(C). Exemption 6 allows a federal agency to withhold “personnel and medical files and similar files the disclosure of which would constitute a clearly unwarranted invasion of personal privacy,” and Exemption 7 permits the withholding of “records or information compiled for law enforcement purposes, but only to the extent that the production of such law enforcement records or information ... could reasonably be expected to constitute an unwarranted invasion of personal privacy.” 5 U.S.C. §§ 552(b)(6), 552(b)(7)(C). Although this court’s review is de novo, because there remains some confusion regarding the exact content of the federal tax lien filings and the various types of personal information that might be contained in even publicly-filed lien documents, this case will be remanded for the district court to take oral testimony, to receive evidence, or to conduct an in camera inspection if it believes doing so would be appropriate and then to make a determination regarding the applicability of these two exemptions. 6 See 5 U.S.C. § 552(a)(4)(B) (permitting but not requiring a district court to examine the contents' of the relevant agency records in camera in order to determine the applicability of any exemptions).
*1083
We do note, however, that certain principles of law with respect to Exemptions 6 and 7(C) have been clearly established. First, Exemption 7 has already been determined to apply not only to information compiled for criminal enforcement purposes but also to that compiled for civil enforcement purposes.
See White v. IRS,
707 F.2d.897, 901 (6th Cir.1983). Second, with réspect to Exemption 6, this court has clearly explained that “a ‘similar’ file [is] not to be construed as encompassing ‘a narrow class of files containing only a discrete kind of personal information;”’ rather, “Exemption 6 [is] to be applied to ‘any Government records on an individual which can be identified as applying to that individual.’”
Heights Community Congress v. Veterans Admin.,
III. CONCLUSION
Since the district court based its decision to deny a FOIA request on inappropriate factors as a matter of law, the judgment of the district court is REVERSED. ■ We remand this case to the district court for consideration of the availability of exemptions in accordance with this opinion, and for any other further proceedings consistent with this opinion.
Notes
. A federal tax lien is a claim by the IRS which arises against all property of a taxpayer who fails to fulfill a tax payment obligation. Notices of Federal Tax Lien are recorded publicly so that the IRS can protect the legal priority of its liens as against other creditors of the taxpayer. J.A. at 73-74 (Hebert Decl. at 1-2).
. An exception should be noted for those cases where "the objection to disclosure is based on a claim of privilege and the person requesting disclosure is the party protected by the privilege.”
Reporters Comm.,
. In an attempt to clarify any confusion that might have existed regarding the exact scope of its request, appellant stated in its final appeals brief that "[n]o request has ever been made for private or confidential information or for information not potentially available in the public domain.” Appellant’s Br. at 3. Appellant insists that it was requesting only federal tax lien information that was already publicly filed and nothing else that might also be contained in the ALS. At oral argument, appellant reiterated this point and further clarified that its request was for either photocopies of documents prepared for *1080 filing or computer print-outs and that it was only interested in receiving records of lien filings pertaining to liens that had not yet been released. It seems appellant has been refining the scope of its request during the course of this appeal such that the nature of its request may now be somewhat different from what had been previously presented before the district court. We leave it to the district court to clarify the time period for which the request is being made and any other details concerning the exact scope of the appellant's request.
. Upon passing this first hurdle, in order to claim protection under Exemption 2, the agency must further show that the public has no genuine or legitimate interest in the requested information.
See Rose,
. The Supreme Court ultimately decided that Exemption 2 did not apply because genuine and significant public interest existed in the Academy's student-run system of discipline.
See Rose,
. In
Vaughn v. United States,
. Hebert did state that information such as a taxpayer's name, address, and "other identifying infoimation” contained in the ALS is incorporated by the IRS into publicly recorded Notices of Federal Tax Lien. J.A. at 74 (Hebert Decl. at 2).
