Deposit Items (Supplemental Data)
Articles in the American Mineralogist can be accompanied by Deposit Items (supplemental or unpublished data and documents). They may include large data sets, bibliographic data or image files. The names and URLs of such supplementary files are given in the corresponding print or online journal papers, and the files are intended to be viewed in conjunction with those papers.
Deposit Items first appeared in American Mineralogist in 1964. From v.49 (1964) through v.53 (1968), 23 items were deposited with the Library of Congress' ADI Auxiliary Publications Project. In 1968 this was changed to the National Auxiliary Publication Service, and 128 items were deposited from v. 53 (1968) to v. 59 (1974). These are now available from Burrows Systems (248 Hempstead Turnpike, West Hempstead, NY 11552, Tel: 516-481-2300). The cost is $15.00 for the first 20 pages, and $0.50 a page for any additional pages.
Starting with v. 60 (1975), MSA assumed responsibility for archiving deposited documents. From v.60 (1975) through v. 83 (1998) paper copies submitted by the authors were microfilmed. Because capabilities for making readable hard copies from microfiche were rapidly disappearing, and customers usually asked for hard copy in preference to microfiche, MSA stopped making microfiche and, starting with v. 84 (1999), only the paper copies submitted by the authors were archived and any electronic versions were posted on MSA's American Mineralogist website.
MSA started retaining the original paper copies of deposited items with establishment of its own Business Office in 1985. MSA had only the microfilm format of items from v. 60 (1975) through v.70 (1984). In 2000 MSA had student worker from George Washington University make print copies of all the documents for which we had only the microfiche, before the library there did away with the fiche printers.
Supplementary material will be placed in MSA's free to use, free to read depository, which is located online. Links to Supplementary material for 1975 to 1999 are below. Supplemental data for 2000 and later articles can be found with the article reference in the Tables of Contents. Click on any Table of Contents, look for a deposit item and click the link).
Almost any content, including tables, figures, and data sets may be deposited and do not have to comply with the official Am Min style guidelines. (Although CIF guidelines are strictly enforced.) In general, deposit materials will appear exactly as the author prepared them. Since deposit material is supposed to last for a long time, use of plain txt, PDF, Excel, or other "universal" formats is advised; but any format is accepted. It would also be beneficial to your paper, if the metadata and branding/header of the item included author(s) name(s), title of the paper, and other keyword information as possible.
