To be able to read PDF documents, you first need suitable software. These so-called PDF viewers (PDF readers) are available as free software. They enable you to display and print PDF documents on all common operating systems. If such software is not yet installed on your computer, you can find out about various PDF viewers independent of providers here and download them free of charge: Wikipedia: Liste von PDF software or at www.pdfreaders.org.
If no PDF reader is installed on your computer, you can view PDF documents directly in the browser. To do so, click on the corresponding symbol of the file attachment. If your browser does not support the software, save the file on your hard drive and open the file from there.
To save a PDF file on your computer ('Download'), click on the file with the right mouse button and then click on "Save target as" with the left mouse button. Select the directory in which you want to save and then confirm with the 'Save' button.
If you would like to print a PDF file, open the corresponding file in your browser and then select the 'Print' option in your browser.
Why we provide PDF documents:
The electronic exchange of files in PDF format does not cause any compatibility problems.
This means: regardless of the operating system on your computer, our texts and forms can be easily displayed - and the high quality is maintained.
The original layout of the document is preserved. There are no layout problems in PDF. No shifting of tables, no unwanted change of font sizes, no unwanted page breaks, etc. The same applies to formatting, colours, fonts and images. They are displayed and printed as they were created in the original.
The search function in the PDF enables you to quickly find text passages, individual terms or even combinations of numbers in order to quickly find the source you are looking for within extensive texts.
PDF files require a relatively small volume of data (bytes). Our PDF texts are usually compressed in such a way that they are sometimes even considerably smaller than the original files (Word files). This saves space on the hard disk and reduces the time needed to download the file.
Our PDF forms can be filled out directly on the computer. If you make a mistake, you can correct it without any problems.

RTF files can be opened with Microsoft Word.

To unpack the compressed ZIP files you need an additional programme such as WinZip www.winzip.com (Windows).
To download TIF files: When saving the files to your computer, please change the file format from "*.tiff" to "*.tif".
