Thanks for your understanding. The biggest help would be if member indexers read through the Indexing manual before they start indexing. I know it is tedious to read instructions and many people prefer to avoid them, but it does make the indexing process so much longer when we have to compose lengthy emails back to the indexer with all the mistakes they made. We're not doing it to make them feel bad, but to ensure those mistakes don't get repeated in the next book (and so our proofreading job becomes much faster).
Recipe types seem to be particularly problematic and they really don't need to be. We recommend having the Recipe types list open in a separate tab when indexing. Then if you aren't sure what Recipe type a dish is, search the list by doing CTRL F - we have listed most dishes under each Recipe type, and we also identify what course it should be and whether it should be listed as Vegetarian/Vegan.
Another of the time-consuming mistakes made by new indexers is assuming an ingredient isn't listed if they don't find it immediately and then listing it as a new ingredient. With 14,500 ingredients in our database you can assume that any common ingredient is listed. If you don't find what you are looking for, try a variation of the words (add or remove a hyphen, try a spelling variation) and also check the Indexing manual for Ingredients which explains why some ingredients are listed the way they are. For instance, cinnamon would never be required as a new ingredient - it is listed as ground cinnamon and cinnamon sticks. And cream of tartar is not listed as it is a store-cupboard ingredient that is never required.
It should get easier as the keen member indexers who have done several books each are now trusted to index without proofreading. So those books can go up quickly which gives us more time to concentrate on the less experienced indexers.
