Baltimore: Enoch Pratt Free Library, 1962-2002. First edition of each. Stapled paperwraps. "Each issue contains one hitherto unpublished item written by H. L. Mencken, original contributions by Menckenthusiasts, and Bibliographic Check List of current Mencken items to form a supplement to the published Mencken Bibliography" (Adler, inside front cover No. 1). IN ADDITION TO THE 151 VOLUMES are 5 issues that were out of sequence with the others (Nos. 141-145) and 19 issues that are DUPLICATES (Nos. 1, 10, 13-15, 17, 18, 20-23, 25-28, 32, 35, 39, and 46), for a TOTAL OF 170 VOLUMES; plus a few ephemeral items (announcements, invitations, T-shirt offers, etc.). Overall, very nearly fine.
