Dеnnis W. Eckes and James Beckett, III, appeal from a judgment of the United States District Court for the Eastern District of New York, I. Leo Glasser, J.,
I.
The schoolyard passion for flipping baseball cards apparently engenders lasting interest for a sizeable part of the population, since this lawsuit arises out of the adult hobby of collecting baseball cards. The facts can be briefly stated: Appellants wrote the Guide, and published it in approximately February 1979. The book was copyrighted and registered. A second edition of the Guide also was copyrighted, registered and issued in approximately March 1980. The Guide is a comprehensive listing of baseball cards manufactured in the 70-year period from 1909 to 1979. Appellees concede that the Guide is the first extensive listing of its kind.
The Guide lists some 18,000 different baseball cards and in each case furnishes the going market price. Some cards are quite valuable. For example, appellant Eckes testified that a set of 407 cards released by Topps Chewing Gum Company in 1952 sells now for $7,000-$8,000, and that the Mickey Mantle card in this group is worth about $800. Each card is listed in a number sequence in each of approximately 100 different sets, with the corresponding price of each card. A set includes all cards of the same type or design produced by a particular manufacturer during a calendar year. The Guide also gives the prices for each card according to its condition: mint, very good/excellent and fair/good. In addition, the cards are placed into twо groups: premium or star cards, and common cards. There are approximately 5,000 of the former, and they are considered particularly valuable because of the player featured on the card, e.g., a hall of famer, a rookie of the year, or because of the team on which he plays, or because of some сharacteristic of the card itself, such as an imperfection or the scarcity of the card. Common cards consist of the remaining cards listed in the series covered.
The Guide is primarily the product of appellant James Beckett, III, a statistician with a Ph.D. in statistics. Beckett had been interested in baseball collecting for some time prior tо producing the Guide, and had written a nationwide price survey of baseball cards. Beckett testified that he worked on the Guide for 40 hours a week for eight straight months. Relying on his extensive knowledge of trading in baseball cards and his background in statistics, Beckett compiled the prices for all the cards and placed them into either the premium or commоn category.
Some three months after the Guide was released, Mark Lewis, a principal of appellee companies, decided to publish a monthly “update” of baseball card prices. Lewis admitted he was “new” to baseball card collecting but claimed the creation of CPU was “a very simple process.” It was so simple, aсcording to Lewis, that it took him only nine weeks to publish the first issue of CPU, including accumulation of informa *861 tion on thousands of cards. CPU was published in a newspaper form, indicated the trends in prices by a plus or minus and listed separately only premium cards; however, its listing contained substantially the same 5,000 cards that the Guide had listed as premium cards. Although CPU appears to list only one price for each card, CPU, like the Guide, actually offers different prices for each card listed. CPU’s “Condition Guide,” located on the inside cover, explains that prices for cards vary according to given percentage multiples, depending on the condition of each card. Though Lewis conceded access to the Guide, testifying it was a “bible” and that “Beckett was the authority,” Lewis vigorously and persistently denied copying from the Guide in producing CPU. Nevertheless, many of the prices and pictures in CPU are the same as those in the Guide, and a number of inadvertent errors in the Guide, including misspellings, inconsistent use of abbreviations and obvious omissions, are repeated in CPU. In addition, therе was testimony of public confusion as to whether CPU was an update of, or otherwise connected with, the Guide.
In June 1980, appellants brought suit in the district court for copyright infringement. After a trial before Judge Glasser, the judge found for appellees. The court characterized Lewis’s testimony as “evasive,” and also found the testimony of appellants’ witnеsses “entirely credible.” The court found the Guide to be a protected work under copyright law and that appellees’ choice of premium cards was sufficiently similar to appellants as to warrant “a suspicion of copying.” Nevertheless, although the judge thought the issue was “extremely difficult,” he held that the “variations” between the two publicаtions iri the prices listed for the cards “render [appellees’] work not so substantially similar as to justify a finding of copyright infringement.”
II.
In this court, appellants contend that the Guide contains the requisite originality to warrant copyright protection, and that there was ample proof of copying. Not surprisingly, appellees disagree on both counts; they particularly press their contention, rejected by the district court, that appellants’ copyright registration is invalid and unenforceable. We consider that question first.
In order to prove copyright infringement, appellants “must show ownership of a valid copyright and copying by the defendant.”
Novelty Textile Mills, Inc. v. Joan Fabric Corp.,
In addition, the court clearly and justifiably believed that appellants’ omissions in the copyright application were inadvertent and innocent. Only the “knowing failure to advise the Copyright Office of facts which might have occasioned a rejection of the application constitute^] reason fоr holding the registration invalid and thus incapable of supporting an infringement

action ... or denying enforcement on the ground of unclean hands____”
Russ Berrie & Co., Inc. v. Jerry Eisner Co., Inc.,
Appellees next argue that the Guidе cannot be protected under the Copyright Act of 1976, 17 U.S.C. §§ 101 et seq. Appellees recognize, as they must, that compilations are specifically protected under the Act. Id. § 103. The Act defines a compilation as “a work formed by the collection and assembling of preexisting materials or of data that are selected, coordinated, or' arranged in such a way that the resulting work as a whole constitutes an original work of authorship.” Id. § 101. Appellees contend, however, that copyright protection does not extend either to the
idea
of a baseball card compilation, id. § 102(b);

Copyright law and compilations are uneasy bedfellows since “the very vocаbulary of copyright law is ill suited to analyzing property rights in works of nonfiction.” Denicola, Copyright in Collections of Facts: A Theory for Protection of Nonfiction Literary Works, 81 Colum.L.Rev., 516 (1981). Indeed, while this court has recognized that the “distinction between fact and expression is not always easy to draw,”

supra,
Nevertheless, our cases do not hold that subjective selection and arrangement of information does not merit protection. In fact, the definition of a compilation in the Act, 17 U.S.C. § 101
(“selected,
coordinated, or arranged”) (emphasis added), the commentators, see, e.g., 1 M. Nimmer, supra, § 2.04[B], at 2-41-2 (“originality involved
*863
in the
selection and/or
arrangement of such facts” protected literary work) (footnote omitted) (emphasis added); Denicola, supra, at 530 (“originality in plaintiffs
selection
or
choice
of data”; Denicola, however, believes that the labor in compiling facts is protected) (еmphasis in original), and the eases, see, e.g.,
Roy Export Co. v. Columbia Broadcasting System, Inc.,
We have no doubt that appellants exercised selection, creativity and judgment in choosing among the 18,000 or so different baseball cards in order to determine which were the 5,000 premium cards. Accordingly, we believe that the Guide merits protection under the cоpyright laws.
III.
The remaining issue before us is whether the district court erred in finding that appellants had not proven that appellees copied appellants’ selection of premium cards. We have held that in the absence of direct copying, “a plaintiff may prove copying by showing access and ‘substantial similarity’ of the two works.”
Novelty Textile Mills, Inc.,
supra,
There was a scarcity of credible, non-self-serving proof in the record of independent creation by appellees. Lewis testified that he did not copy from the Guide, but the district court justifiably found that appellees’ testimony as to the source of its premium price list was “evasive.” The list of 5,000 premium cards in both works is acknowledgеd to be substantially the same, and we believe that it was impossible for appellees to produce the same list without copying. Cf.
Wainwright Securities, Inc. v. Wall Street Transcript Corp.,
Moreover, while there may not have been direct testimony of copying, there was strong credible evidence of it, as noted above, through common errors in the two works. As noted by Professor Nimmеr, “the courts have regarded the existence of common errors in two similar works as the strongest evidence of piracy____” 3 M. Nimmer, supra, § 13.03[C], at 13.38.2-.3 (footnote omitted). See also
College Entrance Book Co. v. Amsco Book Co., Inc.,
In considering the issue of copying, the district court stated that while there were “marked similarities” between the two works, it
must be recognized that since the plaintiffs’ work is regarded as the authority in the field, it is entirely possible that the prices in their publication not only reflect market prices, but in fact can determine market prices. Thus, any subsequent publication accurately reflecting which cards are being traded at a premium would, of necessity, bear strong similarities to the plaintiffs’ work.
Finally, the copying was particularly egregious here because the first issue of CPU used as its “base” prices (the prices CPU was ostensibly “updating” according to its title) the prices actually reported in the Guide. The combination of this with CPU’s appropriation of the premium card selеction of the Guide gave the misleading impression that CPU had actually been authorized to “update” the prices in the Price Guide.
In sum, we find that appellee has infringed protected expression contained in appellants’ Guide. Accordingly, we reverse the judgment of the district court, and remand the case for further proceedings on the issues of damages and equitable relief.
