Stamp Catalogues

Having lamented about catalogues, I still went ahead and bought one. Figured they are more useful for the info they provide than actual pricing. I got a good deal for the Philcent India 2014-15 edition on eBay. Compiled by Prem Chand Jaiswal and published by Philcent Publications, this catalogue provides useful information about Indian stamps, service/revenue stamps, stamps of Indian states, and other postal stationery.
