The copy is fantastic, and the usually horrible nineteenth-century Russian print is in clear, crisp condition.
It is so much easier to search a PDF than microfilm.
This is a wonderful service! I didn't know about this. How very convenient!
CRL fills borrowing requests from member libraries by digitizing individual titles, volumes, or microform reels that can be scanned within five working days (or items too fragile to loan). The scans are rendered in PDF format, incorporating searchable text when the source material supports OCR processing. CRL's digital delivery services offer additional benefits: with advance notice a larger extent of materials can be scanned to meet research or instruction needs, and all digitized items are retained for future consultation by the CRL scholarly community.
This service is designed not only as a convenience to researchers, but also to prevent damage or loss of unique and/or fragile materials in the shared CRL collections. CRL avoids digitizing materials that are otherwise freely accessible in digital format from sources including Google Books, the Internet Archive, and the HathiTrust Digital Library.
