Document Viewer is Lubuntu's
name for Evince - and it comes from their own motto; "Simply a
Document Viewer." The stated goal of Evince is to replace the many
other "portable" document viewers like gpdf and ggv with one,
all-encompassing document viewer. Of course the main format most users
need is the Portable Document Format, PDF. But Evince can
also view djvu, dvi, ps, tif and xps documents and well as comic book
formats; cb7, cbr, cbt and cbz.
Visit Evince's Live GNOME Home and Wiki. Evince is free and open source software licensed under the GPL. Another app we include in the C4C Lubuntu ReSpin is called Xpdf; also free and open source software and also licensed under the GPL. Another good alternative document viewer is called Okular.
Note: Evince, Xpdf (and Okular) are PDF viewers. To create PDF files; the easiest option from most any application is Print-to-PDF. Many applications (some via plug-ins) export to PDF. In LibreOffice Writer; Go to File --> Export as PDF.
If you need to edit an already existing PDF file (ie: you don't have the original), there are other apps that work from the command line (PDFtk), or with a GUI interface (PDF-Shuffler). GIMP has native PDF support - also see Patrick Nagel's solution for multi-page PDF documents here. And LibreOffice has folded their PDF Importer into Draw, where a PDF opens and is editable.
If you need Adobe Reader to read
(not edit) PDF files:
Go to Menu --> System Tools --> LXTerminal
sudo apt-get install
GnuCash is financial
software featuring double-entry accounting, checkbook styled register,
scheduled transactions, reports, graphs and more. Easily import data
from on-line bank statements and other software packages using HBCI,
OFX and QIF files. GnuCash uses the double entry accounting system;
you will always keep at least two accounts balanced. Transfers of
money between accounts debit one and credit the other.
GnuCash divides financial data into files, accounts (checking, savings, credit cards, mortgage, loans...), and transactions (buying something, paying a bill, transferring money, depositing a check, withdrawing money...) stored as either a single XML file or SQL database (using SQLite3, MySQL or PostgreSQL) in five categories; assets, liabilities, equity, income and expenses. And GnuCash makes all this easy to set up and keep track of. You'll always have a good understanding of where you are financially.
GnuCash is free and open source software licensed under the GPL. The GnuCash.org
website features an Online Help Manual and a Tutorial and Concepts Guide. You may be

LIBREOFFICE VS MICROSOFT OFFICE
Microsoft file formats like doc and docx (Word), xls and xlsx (Excel), ppt and pptx (PowerPoint) can be opened, read, changed, and "saved as" in LibreOffice. However, the reverse is not always true. If the LibreOffice user plans to share files with a user of Microsoft Office (or, say print a file from work, turn in a school project electronically, or submit a resume in "Word"); they will probably need to "Save As..." their documents in corresponding Microsoft Office formats.
Writer > Word
Calc > Excel
Impress > PowerPoint
Base > Access
THE "CORE" MICROSOFT FONTS
Special attention should also be paid to the fonts used in LibreOffice documents destined to be opened in Microsoft Office. The "core" Microsoft fonts of Andale Mono, Arial, Arial Black, Comic Sans MS, Georgia, Impact, Tahoma, Times New Roman, Trebuchet, and Verdana are not included. However, these are freely available and easily installed (if you installed the lubuntu-restricted-extras, you now have these fonts).
Go to Menu --> Accessories --> LXTerminal
Type (or copy and paste):
sudo apt-get install
You will be required to agree to the Microsoft EULA. [Tab] to

Base is a powerful database
application. Single users have access to the HSQL relational database
engine with data stored in the BASE file. Wizards help in the creation
of tables, queries, forms and reports. Power users can connect to
almost any database with native support drivers for MySQL, Adabas D,
JDBC, ODBC, MS Access and PostgreSQL. See Base info on LibreOffice.org and Tutorials from
TechRepublic and video tutorials from the FrugalComputerGuy
Calc is the spreadsheet
application for LibreOffice and offers flexible cell formatting
options, multiple user support, security for files, over one million
rows of data (if you need that many in one spreadsheet), plenty of
mathematical functions and easy formula creation. Cross-tabulate,
summarize, and convert raw data from other sources. Use templates
(even those designed for other spreadsheet applications), wizards and
more. There is even an Intelligent
Sum button that inserts a sum function or subtotal, depending
on the context. See Calc info on LibreOffice.org and tutorials from
and video tutorials from TheFrugalComputerGuy.
