"Phycotheca Boreali-Americana. A collection of dried specimens of the algae of the algae of North America", edited by F.S. Collins, I. Holden, and W.A. Setchell, is an exsiccata, i.e., a set of numbered specimens with printed labels. The specimens in an exsiccata are mounted on the pages of what could be considered a scrapbook, each volume with a printed title-page and an index page. Many herbaria have disbound the volumes of various exsiccatae, filing each specimen in its proper taxonomic place. Other herbaria have kept the exsiccatae intact.

From 1895 to 1919, "Phycotheca Boreali-Americana" was issued in 46 bound volumes (I–XLVI, numbers 1–2300) and 5 elephant folio volumes (Fascicles A–E, numbers I–CXXV). Each fascicle, or volume, contains 50 specimens; the elephant folios each contain 25 specimens. The editors were assisted by professional and amateur collectors, including N.L. Gardner, De A. Saunders, H.T.A. Hus, F. Børgesen, Mrs. M.S. Snyder, Mrs. J.M. Weeks, Mrs. C.E. Pease, Mrs. G.A. Hall, and Miss C. Messina. Eighty sets were produced and distributed worldwide (Bot. Gaz. 20: 126. 1895). Thirty-seven sets went to public institutions (Mem. N.Y. Bot. Garden 19: 68. 1969), including NY, FH, BM, PC, TRH, WIS and AHFH.

The University Herbarium at UC Berkeley has two complete sets that belonged to W.A. Setchell and N.L. Gardner. Disbound specimens are filed in the main collection.

First index to the PB-A:
Elizabeth M. Fahey and Maxwell S. Doty assembled and mimeographed an alphabetical index to the Phycotheca Boreali-Americana prepared from the card index at the Marine Biological Laboratory, Woods Hole, Mass. A copy that belonged to E. Yale Dawson is housed at the Smithsonian Institution.
