# Report Book Overview

The main goal of a report book is to combine different reports into one for the purposes of printing them at once or exporting them to a single file. Reports are displayed in the order they were added to the report book, each report starting on a new page.

## Why to use a ReportBook:

* You need to combine multiple reports into a single document for preview, print, and export;
* You need to combine multiple instances of the same report with different settings into a single document for preview, print, and export;
* You need each report to start on a new physical page, sheet in Excel Workbook;
* You need each report to have different [page settings](https://www.telerik.com/products/reporting/documentation/styling/rendering-and-paging/understanding-pagination) like page size and orientation;

## What is a ReportBook

A ReportBook is a class inheriting `Telerik.Reporting.ReportBook`. The `ReportBook.ReportSources` collection allows you to add reports of different formats (XML, TRDX and TRDP files, run-time instances, or classes inheriting `Telerik.Reporting.Report`) into the book, where the Reporting Engine knows how to process the separate reports based on the type of the used [ReportSource](https://www.telerik.com/products/reporting/documentation/embedding-reports/report-sources) for adding them.

> `InstanceReportSource` and `XMLReportSource` cannot be used with the ReportBook.

The [Report Book online demo](https://demos.telerik.com/reporting/report-book) is available also in the local Examples installed by default under `...Progress\Telerik Reporting 2026 Q4\Examples`. An example of how to create a ReportBook instance at run-time can be found in the article [Create a Report Book at run-time](https://www.telerik.com/products/reporting/documentation/designing-reports/report-book/how-to-create-a-report-book-at-run-time).

> When you reference reports stored in the [Telerik Report Server](https://docs.telerik.com/report-server/introduction) in the ReportBook ensure using the *\[CategoryName]/\[ReportName]* path for the URI as specified in the article [Working with Report Server Reports](https://www.telerik.com/products/reporting/documentation/designing-reports/report-designer-tools/desktop-designers/standalone-report-designer/working-with-report-server-reports).
