Someone recently suggested that The Pollen Loads of the Honey Bee by
Dorothy Hodges was "out of print".  According to the latest BooksPlus
catalogue from the International Bee Research Association (IBRA), the
book is still available, at a cost of 30 pounds.  It's well worth owning
if you're into pollen analysis (or classic bee books, for that matter).
 
The IBRA has also published another excellent pollen identification
book.  It's called A Colour Guide to Pollen Loads of the Honey Bee, by
William Kirk.  It's also available from the IBRA, at a cost of 13 pounds
50.  This book has two advantages.  First, it's multilingual (English,
German and French).  Second, it uses the CMYK screen tint percentages,
as used by printers in the four-colour printing process.  So the colours
for pollen loads are standardised.
