BooksCloud carries over two million titles from more than 30,000 publishers. When you run a bulk sync, a reasonable question is: does the sync reach across the entire catalog, or is it limited to some pre-curated subset?
The answer is that the bulk sync draws from the full catalog - but what actually lands in your store is shaped entirely by the filters you apply before the sync runs. Understanding how those filters work is the key to getting a clean, relevant product list without importing titles you will never sell.
The Full Catalog Is the Starting Point
BooksCloud's 2M+ catalog is the pool that every bulk sync draws from. There is no hidden tier of "sync-eligible" titles versus "browse-only" titles. Everything available in the BooksCloud catalog is available for bulk import, provided it meets the filter criteria you set.
This is a meaningful distinction from some dropshipping platforms where bulk tools only access a curated, smaller subset of inventory. With BooksCloud, you are working with the full depth of a catalog sourced from tens of thousands of publishers.
Filters Are What Shape Your Import
When you set up a bulk sync, BooksCloud gives you several filters that act as gates on which titles come through:
Category. You select which genre or subject category you want - Fiction, Business, Self-Help, Children's, and so on. Only titles tagged under that category in BooksCloud's system will be included.
Cover type. You can filter by hardcover, paperback, or both. This lets you match the format preferences of your customer base.
Language. If your store serves a specific language market, you can limit the sync to English-only titles, or include other languages as needed.
In-stock status. You can filter to only import titles that are currently in stock, which prevents you from listing books you cannot actually fulfill right now.
Bestseller percentile. This is one of the more powerful filters. It lets you import only titles that rank within a certain percentile of bestseller performance - for example, the top 10% or top 25% of sellers in a category. This is how you can skip the long tail of obscure titles and focus on books with proven demand.
What a "Category" Sync Actually Covers
When you sync a category like "Fiction," you are telling BooksCloud to pull all in-catalog titles tagged under Fiction that also meet your other filter criteria. Depending on how broad the category is and how permissive your filters are, this could mean hundreds or tens of thousands of titles.
Sub-categories are also available. Rather than syncing all of Fiction, you might sync "Mystery & Thriller" as its own category - which brings in a more targeted set of titles without manually excluding the broader fiction you do not want.
One review from a BooksCloud user captures this well: "Great app, has bulk add feature, and a large selection of books." The selection is large precisely because it draws on the full 2M+ catalog, not a curated shortlist.
How to Use This Practically
If you are just starting out, the bestseller percentile filter is your best friend. Syncing the top 10-20% of bestsellers in your chosen category gives you a tightly relevant catalog of proven titles without flooding your store with low-demand inventory.
As your store grows and you understand your audience better, you can run additional targeted syncs - perhaps adding a sub-category, loosening the bestseller filter, or including a second language - to expand your catalog strategically.
The full 2M+ catalog is always there waiting. Your filters determine how much of it you bring in, and when.
