This case arises out of the efforts of the Church of Scientology of California to obtain documents from the Internal Revenue Service under the Freedom of Information Act, 5 U.S.C. § 552 (1982) (“FOIA”). It requires us to review the District Court’s grant of summary judgment to the IRS on the adequacy of its response to the Church’s FOIA request. To do so we must consider, among other things, the relation between FOIA and the provisions of the Internal Revenue Code that govern disclosure of return information, 26 U.S.C. § 6103 (1982).
I
On May 16, 1980 the Church sent a Freedom of Information request to the IRS. It comprises seven single-spaced typed pages and is extremely confused, but for purposes of this appeal it has been adequately summarized by the Church as essentially requesting:
1. All documents or records “relating to or containing the names of Scientology, Church of Scientology, any specific Scientology church or entity identified by containing the words Scientology, Hubbard and/or Dianetics in their names, L. Ron Hubbard or Mary Sue Hubbard,” which could be located in a number of systems of records or files specifically identified in the FOIA request, “including but not limited to those located at the National Office, Regional Offices, Service Centers, District offices or Local IRS offices.”
2. All documents generated, received or which otherwise came into the possession of the IRS subsequent to the preparation of an index in a tax case involving the Church of Scientology of California pending in the United States Tax Court,
*148
Church of Scientology of California v. Commissioner of IRS
[
Brief for Appellants at 1-2.
The IRS’s first response, dated July 22, 1980, requested additional time to “locate and consider releasing the Internal Revenue Service records to which you have requested access” and estimated that the Service would respond on August 29. On September 17,1980, a response still not having been received, the Church filed an appeal to the Commissioner. After the IRS acknowledged but failed to resрond to the appeal, the Church filed a complaint in the United States District Court for the District of Columbia on December 18, 1980 under 5 U.S.C. § 552(a)(4)(B) (1982). In January 1981 the IRS finally responded to the Church’s request with a letter. For the sake of simplicity, we will limit our summary of that response to those factors that have some bearing on the issues here.
The IRS noted that it had limited the scope of the Church’s request to documents pertaining to the California Church because the Church had not provided authorizations from any other Scientology entity nor from the Hubbards. Geographically the Service had limited the search to the National Office, the Covington, Kentucky, office and the Los Angeles office. The IRS claimed that all documents relating to the Tax Court case not previously released were exempt from disclosure under Section 6103(e)(7) because disclosure would seriously impair Federal tax administration. It released in full somе national office documents acquired subsequent to the Tax Court case index, but justified only partial release of other National Office documents on grounds that they were outside the scope of the appeal, that their disclosure would cause a clearly unwarranted invasion of privacy, see 5 U.S.C. § 552(b)(6), or that they reflected return information of third parties, see 26 U.S.C. § 6103(a).
After the IRS answered the complaint, the Church moved for an order requiring the IRS to prepare a
Vaughn
index of the withheld documents,
see Vaughn v. Rosen,
II
The first issue we must address is the relation between FOIA and Section 6103. The Church argues that Section 6103 gives rise to an exemption from disclosure only under FOIA Exemption 3, 5 U.S.C. § 552(b)(3), and subject to the procedural provisions of FOIA, including its de novo review requirement. The IRS urges us to affirm the District Court’s holding that Section 6103 totally supersedes FOIA and provides the exclusive criteria for release of records affected by that section, so that courts must uphold any IRS refusal to *149 disclose under Section 6103 that is not arbitrary or capricious and does not violate the other provisions of the Administrative Procedure Act.
The IRS relies principally on
Zale Corp. v. IRS,
From what has been said, it should be clear that we do not share
Zale’s
concern over our “duty to reconcile” FOIA and § 6103,
Ill
The Church objects to the IRS’s decision not to search the files of its regional and district offices other than those in Los Angeles and Covington, Kentucky. FOIA requires agencies to make records available in response to any request “made in accordance with published rules stating the time, place, fees (if any), and procedures to be followed.” 5 U.S.C. § 552(a)(3)(B). The IRS does not have a central file of records in which copies of all documents in its possession are retained. Its regulations therefore require requests to be made to the office of the official who is responsible for the control of the records requested, qr if the person making the request does not know the official responsible, to the office of the director of the IRS district office in the district where the requester resides. 26 C.F.R. § 601.702(c)(3)(iii) (1984). The regulations specify in some detail which officials are responsible for documents and give their addresses. 26 C.F.R. § 601.-702(g).
It is undisputed that the Church did not direct its request to the officials in charge of the documents in regional and district offices, nor to the office of the director of the IRS district office in the district where the Church resides, but rather to the National Office of the IRS. The Service caused a search to be made of the records in its National Office, and in addition (though it was not technically required) of the records in the two field offices particularly pertinent to the Church’s operations. In view of the statutory command that requests be made in accordance with published rules, the clarity of those rules, and the reasonableness of the IRS’s treatment of the misdirected request, we find no merit in the Church’s contеntion that the IRS’s failure to inform it earlier that the request for a search of all district and regional offices was misdirected should have led the District Court to require a search of those offices.
IV
The Church also challenges the IRS’s decision to limit the search to files whose titles refer to the California Church. That decision involved two separate but related limitations: (1) restricting the search to those files whose subjects indicate that their contents аre related to Scientology, the Hubbards, etc., rather than searching through all files, whatever their subject, that might contain some information responsive to the request; and (2) restricting the search further to those files whose subject is the California Church on grounds that the information in all requested files on other Scientology organizations, the Hubbards, etc., is return information and therefore exempt from disclosure to the California Church.
The IRS justifies the first restriction on grounds that a request for all information on Scientology in its files fails to meet the statutory requirement of “reasonably describing] such records,” 5 U.S.C. § 552(a)(3). It is firmly established that “an agency is not ‘required to reorganize [its] files in response to [a plaintiff’s] re
*151
quest in the form in which it was made.’ ”
Goland v. CIA,
But the first limitation was in any event superseded by the limitation to records of the California Church. The IRS does not appear to dispute that the Church’s request reasonably describes information directly relating to some other Scientology organizations and contained in files whose titles would enable identification without undue burden. Its decision not to search these files appears to rest exclusively on grounds that they contain only return information protected by Section 6103.
The Church asserts that these grounds are patently inadequate, since (1) return information consists only of data that identify or can be associated with the taxpayer to whom they pertain, (2) FOIA’s requirement that “reasonably segregable” portions of otherwise exempt documents must be provided, 5 U.S.C. § 552(b), would mandate production of the data after redaction of materia] that enables identification or association, and (3) the possibility of redаction can only be assessed on a document-by-document basis. The crucial first premise of this argument has been considered by this court en banc and, by an opinion issued simultaneously with the present opinion, has been rejected.
Church of Scientology v. IRS,
This is still not sufficient, however, to sustain the IRS’s bald contention that it need not search the file of any Scientology organization other than the California Church. That contention would be justified only if, as a matter of law, all information in IRS files is return information. That is unquestionably not so. Congress would not have adopted such a detailed definition of return information in Section 6103 if it had simply intended the term to cover all informаtion in IRS files; and we have no authority to substitute the one disposition for the other. Here the Church requested, for example, information from Treas/IRS System Number 26.005, “File of Persons Making Threats of Force or Forcible Assaults.” If such a files system exists, it seems unlikely that its contents consist en *152 tirely of return information as defined in Section 6103. In any case, before the IRS’s claim that all information in the requested files is protected can be upheld, it must make an appropriate showing that all information comes within the statutory definition.
For the reasons just given, the District Court erred in accepting the IRS’s blanket assertion that all information responsive to the Church’s request in files not relating to the California Church was exempt from disclosure. This does not mean, however, that the IRS must, as the Church would have us hold, prepare a
Vaughn
index of all documents in its files relating to third parties for which it claims an exemption under Section 6103 and Exemption 3.
See Vaughn v. Rosen,
In light of the foregoing discussion, the IRS must either conduct a new search for information responsive to the Church’s request that refers to third parties or establish through affidavits that all information about third рarties in identifiable files requested by the Church is generically protected by Section 6103. If a new search produces any third party information responsive to the Church’s request, the IRS must either disclose it or justify withholding it in light of one of the FOIA exemp *153 tions through affidavits and, where necessary, Vaughn indices.
The IRS’s search uncovered a large number of documents responsive to the Church’s request and relating specifically to the California Church. It claimed exemption for the majority of these documents — concrеtely the Tax Court case documents — on the ground that disclosure “would seriously impair Federal tax administration,” 26 U.S.C. § 6103(c). Selected portions of a much smaller group of documents not related to the Tax Court case were withheld under various FOIA exemptions because they contained personal information or third party return information, or because they exceeded the scope of the Church’s request. The Court upheld the IRS’s claim of exеmption on the basis of

The order of the District Court is vacated and this case is remanded to the District Court for further proceedings consistent with this opinion. At the conclusion of such proceedings, the Church may renew its motion for an award of attorney fees if it so desires.
So ordered.
Notes
. In its opinion,
Church of Scientology of California v. IRS,
, We do not suggest that an earlier Congress can limit the manner in which a later Congress may express its legislative acts. This provision, like any other, can presumably be repealed by implication. But it assuredly increases the burden that must be sustained before an intent to depart from the Administrative Procedure Act can be found.
. The District Court does mention that the IRS indexed twenty-one documents located in its National Office, but its opinion seems to suggest that the court relied entirely upon
in camera
examination.
