Since there is at least a small chance you may not be trolling......Regarding whether you should buy AFIP fascicles, general reference texts, or WHO Classification books, it depends on the subject area of interest.
If my intention was to build a general reference library, starting from scratch, that'd be sufficient for >99% of what a general pathologist needs, I'd buy the following--preferably in electronic format, where available:
- Rosai and Ackerman's Surgical Pathology. This book alone has 90% of what you need. If I had to pick one, this would be it.
- Blaustein's Pathology of the Female Genital Tract
- Edzinger and Weiss's Soft Tissue Tumors
- McKee's Pathology of the Skin
- Cibas's Cytology: Diagnostic Principles and Clinical Correlates
- WHO Hematopathology book. Skip the other WHO books unless you have extra cash.
- Katzenstein's surgical pathology of non-neoplastic lung diseases
- Lefkowich's Liver biopsy interpretation
- If I had any money left I'd buy:
- Fletcher's Diagnostic Histopathology of Tumors (if you do a lot of tumor cases.)
- Russell and Rubenstein CNS pathology book
The AFIP fascicles are great for identifying rare entities, but I wouldn't buy them unless I had a very solid general reference library already and had money to spend. In my view, the Amirsys products are nice, but again, wouldn't buy them unless I had everything else. The WHO Classification books vary widely in their quality and usefulness for daily practice.
