The source file is ca. 16 megabytes and consists of ca. 50,000 records. The source file is available via anonymous ftp at ftp://ftp.umdl.umich.edu/pub/MEMEM.zip. This compressed file contains the materials, the DTD used to construct the materials and the character DTD.
The main file is also available from the Oxford Text Archive under the catalog number A-1693-E (the original, untagged files are A-171-E).
Corresponding print and microform publications exist for these materials. The main body of entries (36,000 modal verbs) can be found in: Michigan early modern English materials, Richard W. Bailey, James W. Downer, Jay L. Robinson, with Patricia V. Lehman. Ann Arbor : Xerox University Microfilms in cooperation with University of Michigan Press, 1975.
Enhancements to the system are planned.
