A question: Are there any working examples of the following approach to providing access to digital images? 1) Making lo-rez images available on the Internet as part of a working collections database (in this case a natural history research collection.) 2) Selling hi-rez images through : a) fee for access on the internet (ie credit card or account payment.) b) selling CD-ROM's So, a researcher would find the specimen that s/he is looking for by searching the database. A low resolution image of this specimen would be immediately available (good enough to confirm the general appearance of the specimen.) Then, the researcher could either click to pay for immediate access to a hi-rez image (a fee would be charged to his/her institution, or if they hadn't an account, a credit card would be requested.); or alternatively, buy the CD-ROM at a cost comparable to the research CD-ROMS that are now available.
